If you are wanting to study abroad, then you really should research into obtaining a scholarship. Unfortunately my knowledge of this is very limited at best and maybe someone with a greater understanding could better assist you in this area.

However, I will do some research of my own and look for schools which are better suited for your finanacial needs.

Those costs are just for tuition and refer only to in-state students. I mean the least you could do is quote your source:
